Bound sovereign: Reincarnated with the lust system

The oak door clicked softly behind him as Eran stepped into the office. The scent hit him first—warm parchment, faint perfume, and something sharper, something that lured him deeper. His eyes lifted, catching Selene's figure poised by the desk, the lamplight stretching golden shadows across her silk blouse clung to every curve beneath the flowing robe, the soft fabric outlining what the regal garment tried to hide."

She looked up the moment he entered, her eyes darting to his and in that instant the System purred inside his mind.

Eran's lips curved slowly. He didn't need to rush. He already felt the odds stacked neatly in his favor.

"Professor Selene…" His voice was low, measured, carrying just enough velvet to sink under her skin. He let the silence stretch a heartbeat before he added, "I think I should want to… learn more from you."

Selene blinked, caught off guard by the way he phrased it. Her gaze held his for a moment too long, her throat working as if she had forgotten how to breathe. Something in his eyes, something unreadable, almost dangerous.. made her fingers tighten faintly on the papers she held.

"You're… eager," she replied softly, setting the pages down. She tried to compose her features, to keep her professional air intact, but her body betrayed her with the subtle shift of her stance, the quiet intake of breath.

Eran stepped closer, not fast, not slow, just enough to let her feel the deliberate weight of his presence. He tilted his head, studying her like one might a puzzle he had already solved.

"Isn't that the point of a student?" he asked. "To seek… knowledge?" His smirk deepened, eyes dropping briefly to the curve of her blouse before meeting her gaze again. "Especially when the teacher is worth learning from."

Her breath caught. Just a flicker, but enough for him to notice.

Selene turned slightly, leaning back against the desk as if for balance. "Careful," she murmured, but her voice lacked conviction. "Words like that can… lead to misunderstandings."

"Misunderstandings," Eran echoed, closing the gap between them by another careful step. His hand brushed the desk near hers, close but not touching. "Or truths we don't dare to speak aloud?"

Her eyes widened for just a second, lips parting. The lamplight caught the faint flush creeping along her cheeks. She tried to avert her gaze but failed. his stare was too steady, too assured.

The SYSTEM flared again...

Lust Rate: 48%

Desire Level: 92%

Target heartbeat accelerated. Desire indicators: High.

Selene shifted, her thigh brushing against the edge of the desk, her blouse pulling slightly as she moved. Eran didn't miss the tremor in her breath.

"You're… playing with fire," she whispered, as if the words were meant for herself more than for him.

Eran leaned in, his voice just low enough to stir the skin near her ear. "Then maybe you should tell me to stop."

She froze. Her hands curled faintly at her sides, lips pressing together, eyes flickering like searching for something—authority, restraint, anything to anchor her. But nothing came.

Instead, she whispered, "You shouldn't… tempt your professor this way."

And Eran smiled because the words were not rejection. They were confession.

Lust Rate: 55% Threshold Approaching…

He pulled back slightly, just enough to look at her, his expression still carved with that dangerous calm. "Then let me be clear," he said softly, almost like a vow. "I want to tempt you. I want you to surrender to me."

Her breath hitched, her chest rising as though her body betrayed her faster than her mind could resist. Her eyes locked to his, wide, flustered, trembling in something dangerously close to anticipation.

For the first time, she looked like she might break.

"I… don't…" she started, but her voice cracked, too frail to convince even herself.

He leaned just slightly closer, his words a dark caress. "Professor… when the lesson begins, I won't let you walk away unchanged."

Selene's lips parted, no sound escaping, her entire frame tense with heat she didn't want to admit. And still she didn't push him back.

The office was silent except for their breaths, the tension coiling, the space between them shrinking into nothing. The game was his now. He knew it.

Her lips parted but no refusal came. No push, no slap, no reprimand. Just silence… and her shallow, betraying breath.

Eran's smile deepened. The system pulsed at the edge of his vision.

Lust: 96% — Critical Point Approaching…

Desire Level: 92%

Her robe slipped slightly at the shoulder, exposing the soft line of her collarbone. She could have pulled it back, could have stepped away. She didn't.

Instead, Selene's body swayed, so slightly toward him.

Eran's fingers trailed upward, brushing against the fabric that separated him from her warmth. "You're trembling, professor," he murmured, his voice velvet and sin. "But you haven't pushed me back."

Her throat tightened. She hated herself for the way her heart thundered, for the way her body ached in places she'd buried behind iron walls of discipline.

"…I should…" she whispered, her voice breaking. "I should stop this."

But her body leaned closer still.

The system purred.

[Auto-Trigger: Forbidden Yearning]

Selene's Lust Surge 97%

Status: Her body betrays her mind.

Eran lowered his head until his lips brushed the shell of her ear, just enough to make her knees weaken. His breath was warm, a cruel caress against her resolve.

"Then stop me," he whispered. "Push me away, Selene. Tell me you don't want this."

Her breath caught. The words were there, she knew they were, but they never came.

Instead, her hands—traitorous, trembling hands.. gripped the edge of his sleeve like afraid of him leaving.

Eran smirked.

"Exactly what I thought."

Her lashes fluttered, her cheeks flushed crimson, and her thighs pressed together as though seeking relief she refused to name.

"…You're dangerous," she whispered, her voice barely audible.

His lips finally brushed against hers, soft, testing, electric. Just a whisper of a kiss. Enough to draw a sharp gasp from her throat.

Her head tipped back against the desk, her lips parting helplessly as her body betrayed her last wall of restraint. She wanted him-all of him.

"…Eran…" she whispered, her voice breaking into confession, "don't stop…"

And that was the moment the power shifted completely.

Her whisper "don't stop"—was all the permission he needed.

Eran's lips crushed against hers, no longer testing but claiming. Her gasp melted into him, her hands gripping his shoulders as if the desk beneath her couldn't hold the weight of her surrender.

His fingers slid to her thigh, firm, insistent, guiding it apart. Her robe loosened like the fabric itself wanted to betray her, slipping from her shoulders until the pale swell of her breasts spilled free, quivering with her ragged breaths.

Selene's eyes widened. Her hands twitched to cover herself, but Eran caught her wrists, pinning them against the desk.

"You don't hide from me," he murmured against her lips. "Not when your body has already told me everything."

"I—I…" her voice broke, her cheeks blazing crimson. "I can't—"

"You can," he corrected darkly. "And you will. Because you're mine now."

Her breath hitched as his hand traced down the plane of her stomach, slow, deliberate, before sliding beneath the silk of her panties.

A strangled moan tore from her throat. "ERAN…!"

Her silk clung to her heat, soaked through. His fingers teased circles over her swollen clit, her hips jerking, betraying the very resistance her mind tried to muster.

"See how your body begs?" Eran whispered, his lips brushing her jaw. "I don't even need to take you fast. I could keep you here all night, trembling… dripping… begging for mercy you'll never get."

Her head shook, but her moans betrayed her. "N-no… I—AHHH—if you do that—I'll…"

"Cum?" His smirk deepened, wicked and merciless. "Then cum for me, Selene. Show me how badly you've fallen."

Her thighs trembled violently, her back arched against the desk, and the dam inside her broke. A raw cry burst from her lips as her body convulsed, soaking his fingers in her surrender.

The system chimed in triumph:

[First Orgasm Captured]

[Reward: +50 IP | +1 Skill Token]

Selene Nightveil the Ice-Serpent —

Bound to Host's Harem (Rank I)

Eran withdrew his soaked fingers, watching her pant, her chest heaving, her lips trembling between shame and desire. A dangerous smile curved his lips as he leaned close, brushing her ear with a whisper.

"I haven't started yet."

Her eyes widened in dazed shock right before he gripped her panties, tearing them aside. Her bare, dripping heat glistened in the dim office light, and she bit her thumb in humiliation, her face burning.

"…you're too thick," she whispered, trembling as his tip pressed against her folds, her walls already clenching in anticipation.

"Say it properly," Eran ordered, his voice like velvet chains.

Her thighs spread wider, betraying her completely. "…you're so thick, Eran… I—I can't take it—"

His smirk was merciless. "Oh, you'll take it. Every inch."

And with one slow, claiming thrust, he slid inside her....
